title: [Health-related regulation of diethyl phthalate, di-n-hexyl phthalate and dialkyl phthalate 810 in water].
abstract: On the basis of studies of hygienic regulation of diethylphthalate (DEP), di-n-hexylphthalate (DHP) and dialkylphthalate-810 (DAP-810) in the water medium) it has been found out that the compounds are highly persistent in the water medium, are of low toxicity (LD50 from 10.3 up to 33 g/kg and more for white rats), belong to the third and fourth (DHP and DAP-810) classes of danger. The threshold concentrations of DEP, DHP, DAP-810 according to the organoleptic water properties and sanitary regimen of water reservoirs were determined on the level of 1, 0.46, 0.3 and 0.1, 1, and 1 mg/l respectively. DEP has moderately expressed cumulative properties while in DHP and DAP-810 they are clearly expressed. No specific effect was observed in the compounds. MACs for DEP, DHP and DAP-810 in the water medium are recommended on the level of 0.1, 0.5 and 0.3 mg/l according to the general toxic and organoleptic indices of harmfulness.
